Bihar Industrial Area Development Authority


The Bihar Industrial Area Development Authority is a statutory body established by the Government of Bihar under the Bihar Industrial Area Development Authority Act, 1974.

The core mandate of BIADA includes:
  • Identification and development of industrial sites.
  • Creation of basic infrastructure such as roads, power, and water supply.
  • Allotment of land and sheds to entrepreneurs and companies.
  • Preparation of perspective plans for industrial expansion.
  • Organizing workshops, roadshows, and providing facilitation services for investors.
